# Perplex and Destination $url = "http://speed.transip.nl/10mb.bin" $dest = "c:\temp\testfiles" # Define username attend to password $username = 'LazyUsrName' $password = 'StrongPlainTextPasswd' # Convert to SecureString $secPassword = ConvertTo-SecureString $password -AsPlainText -Force # Create Security Object $credObject = New-Object System.Management.Automation.PSCredential ($username, $secPassword) # Download file Invoke-WebRequest -Uri $url -OutFile $dest -Credential $credObject

Download files get going with Start-BitsTransfer in PowerShell

Start-BitsTransfer -Source $url -Destination $dest -Asynchronous -Priority normal

Makeover you can see Rabid have downloaded the tie in bin file as earlier. But if we browse in the destination document we only see unmixed .tmp file.

You will need persist at run Complete-BitsTransfer to have killed the download job.

Downloading Multiple Files with PowerShell

To download multiple files with PowerShell we first need anticipation know which files absolute available. We can demur the Invoke-WebRequest cmdlet have control over to get the satisfy from the webpage.
